CENTRIFUGAL MACHINE. f

i i `plllcation led IlVIay` 13,

This invention has 'reference ,to certain improvements which I have introduced into centrifugal machines, suchpas arenow in use for the manufacture of pile sugar, these improvements having for their object that of making? moreeasy and rapid the operafv tion of extracting the lumps of sugar. V

In the centrifugation .of pile sugar there is at present a difficulty anda considerable loss of timeyinvolved in having to loosen the moulds which divide up the lumps of sugargin; order 'that they may be taker-lout easily. Even after the removal of the moulds, the lumps of sugar generally `remain adhering to the sides Iof' the drum, making the work f of taking them out more diflicult.

To overcome this dii'liculty, I have superposed a ring, which, by means of a special mechanism lis lifted at` will on completion ofv the centrifugation, thus loosening` the lumps of sugar and the moulds interposed between them.

The object of the presentfinvention is that of detaching the lumps of sugar from the interior walls of the drum by means of a superposed ring, whichis lifted byvmeans p of a special mechanism, consisting of a combination of levers arranged radially, or

some other suitable arrangement, beneath the rincipalbase 0f the-centrifugals.

f ith the presentinvention the following objects are attained A l Y v 1st. The lifting of the superposed ring by means of a screw. thus producing a smooth, secureflift, without jars.

2nd. The placing of the levers beneath the principal basa-thus making possible the perfect seating of the superposed ring on the upper part of the principall base,vover the whole surface, makingimpossible the entry of the cooked mass between Athe two points where the lumps f 192e. serial No. 198,843.

Fig.- 2, isvan elevation of the sameyprojected in central vertical section.

Referring to the drawings A is the screw which works in the upperextremity of the axle B, and Lhas a part of its head let Yinto lthethimble C, to whichis joined the'bellshaped cover D. This screw "secures at will n the axialdisplacement of the iiange'E conjointlywith the vvertical arms F, suitably aflixed tosame. l Y Y' kkThese arms exert pressure upon the raised extremity of their respective levers Gr. which oscillate on the fulcrums H and which, have vfor their object the lifting of thefpins I. The pins I, passing through the principal` base J, vcause the lifting of the ring K which is superposed on the said base.

The working is as follows: ,Y

When the usual period of centrifugation is completed, the screwrl is turned, by means of a key, and moved so thatit descends, By this movement, the parts C,

D, E, and the arms F are forced to descend.,v The lower extremities of the arms F, .each

press' upon its vrespective lever C. which,- being balanced ,upon the pins or fulcrums H, suitably securedto the lower wall of the principal base, cause the other extremity to lift the pins I, which in turn lift the ring v p By this simple operation, the easy and rapid removal and detachment of the lumps of sugar from the'walls of the drum isobtained. f

The elements described may vary in their lconstructional form according to the capaci-- ero ity and construction. of the centrifugals to which are to beapplied the improvements which arethe object of this application.
